How do i remove anytime calls package on my home phone?

When i joined Virgin media on my home phone i added anytime calls package with an extra 8 pounds and now i can see that i am paying this money for no reason at all because i hardly use it. I am using my mobile phone all the time. I would like to know how i can remove the package and stay on the standard one. Thanks
